DETAILED DESCRIPTION OF THE INVENTION

In order that those skilled in the art can further understand the present invention, a description will be described in the following in details. However, these descriptions and the appended drawings are only used to cause those skilled in the art to understand the objects, features, and characteristics of the present invention, but not to be used to confine the scope and spirit of the present invention defined in the appended claims.

With reference to FIGS. 1, 2 and 3, the present invention will be described herein.

The present invention includes a spraying tube 3 and a faucet body 2 connected to the spraying tube 3.

A faucet body includes a first water supply unit and a second water supply unit.

The first water supply unit has the following components.

A ceramic valve tank for embedding a water control ceramic valve 21 is installed at a front protrusion of the faucet body 2.

A cold water input tube 21A and a hot water input tube 21B are installed at a front bottom of the ceramic valve tank. A rear side of the ceramic valve tank has a water supply opening 221. Water can flow through the supply opening 221 to a rear water chamber 22 so that the cold water W1A or hot water W1B can flow through the main hole 231 of the water chamber 22. Then the water flows out from an outer tube 31 of a coaxial tube 3 by an adaptor seat 23A.

The second water supply unit has the following components.

An inner tube 32 of the coaxial tube 3 is installed to a sub-seat hole 232 below a main seat hole 231. A water cleaning chamber 24 below the inner tube 32 is isolated by a first isolating plate 241 having a water inlet 242.

A cold water inlet tube 243′ has a cold water inlet hole 234 at an upper side thereof. The cold water inlet tube 243′ is connected to a lower cold water chamber 24B through the cold water inlet hole 243. Cold water W2A flows through the cleaning water inlet hole 243 to the lower cold water chamber 24B. The water W2A flows through the water inlet 242 to the upper water chamber 24A and then flows into the inner tube 32 of the coaxial tube 3.

A cold water control valve 25A serves to control the opening between the lower cold water chamber 24B and the upper chamber 24A so that the water flows into the upper water chamber 24A.

A hot water control valve 25B arranged opposite to the cold water control valve 25A for controlling hot water flow. Cold water flows from the upper water chamber 24A to the water guide chamber 26 from a middle water hole 262. An isolating plate 261 serves to separate the guide chamber 26 from the cold water chamber 24B. The middle water hole 252 is on the guide chamber 26.

A guide tube 262′ is connected below the guide chamber 26. Cold water flows into the guide tube 262′ from the guide chamber 26 and then to a process tank, for example, an electric heating tank (not shown) through a guide opening 263 for heating the water.

Referring to FIGS. 3, 3-A and 4, it is illustrated that the isolating surface 241 has a folded structure.

The first isolating plate 241 and the second isolating plate 261 are formed with a longitudinal channel 24R with two openings 24R1 and 24R2. A hot water tube 27 is installed between the openings 24R1 and 24R2 by using an upper sleeve 271 and a middle sleeve 272. The lower end of the hot water tube 27 is inserted into the processing tank so that hot water can flow through the hot water tube 27.

In operation, when only hot water is desired, then the cold water valve 25A is closed so that cold water will not flow into the upper chamber 24A. Only the hot water flows into the inner tube 32 so as to further flow into the spraying tube 3.

When only cold water is desired, the hot water valve 25B must be closed so that only cold water flows into the inner tube 32.

By adjusting the opening of the hot water and cold water valves, the temperature of the mixing water in the upper chamber is adjusted.

The present invention is thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the present invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
